SPECIFICATION forming part of Letters Patent No. '7 55,494, dated March 22, 1904.

Application filed February 13, 1902. Serial No. 93,921. (No modelJ i To all whom it may concern:

Be it known that I, RUDoLF HORNSTEINER, manufacturer, a citizen of Austria, residing at Prague-ZiZkomProvince of Bohemia, Austria- Hungary, have invented certain new and useful Improvements in Machines for Producing Cylindrical Tubes and Tube-Like Paper Objects with Bottoms Obtained by Bending in the Envelop; and I do hereby declare the following to be afull, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a paperguiding device for guiding the paper fromthe rollers to the mandrel in tube-forming machines.

This device comprises, essentially, parts somewhat similar to each other, one of which draws the paper off from a roller and guides it through a device to the second part, which latter after separating the part of the strip in question guides it to the Winding device or tube-forming mandrel.

The accompanying drawings illustrate the device in question. T

In the drawings, Figure 1 is a top view of the device in that position at which the two parts are in the rearward position; Fig. 2, a similar top view to Fig. 1, but showing the parts moved farthest forward. Fig. 3 is a vertical section through the device on the line A A of Fig. 1; Fig. 1, a similar section on line B B of Fig. 1; Fig. 5, a similar section on line C Oof Fig. 2. Fig. 6 is a vertical section on line D D of Fig. 1. Fig. 7 is a top view of the guide-frame; Fig. 8, a top view of one part of the shifter lying at the right in Fig. 1. Fig. 9 is a section on line E E of Fig. 8; Fig. 10, a top view of the clampingbar arranged upon the shifter, Fig. 8; Fig. 11, a top view of the shifter, Fig. 8, with the clamping-bar. Fig. 12 is a section on line F F of Fig. 11. Fig. 13 shows a top view of the second shifter at the left in Fig. 1; Fig. 14., a section on line G G of Fig. 13. Fig. 15 is a top view of a second shifter secured on the shifter, Fig. 14., and displaceable crosswise of the same. Fig. 16 is an end view of Fig. 15.

Fig. 23 shows a top view, and Fig. 24 a longitudinal section of the counter-lever belonging thereto. Fig. 25 is a cross-section on line H H of Figs. 6

and 21.

The device consists, as shown in the drawings, of two parts quite similar to each other, of which the part at the right hand in Fig.1 performs the function of taking off and measuring the strip of paper to be cut off; but the part at the left hand, on the contrary, operates to clamp the free end of the strip during the cutting off and guide the piece cut off to the tube-forming mandrel. Each of these parts consists of a shifter movable in its longitudinal direction and a clamping-bar, which latter can hold the paper fast upon the former. T 1 designates a driving-shaft of the machine, upon which is a grooved disk 2, which on turning through the medium of its groove 3, engaged by a roller 4, puts into alternate motion a shifter-rod 5, that is guided inastraight line. This rod 5 actuates two double-armed levers 8 and 9, capable of oscillating around bolts 6 and 7, of which the first, 8, actuates the right-hand and the latter, 9, the left-hand part of the feed device.

On the table-plate of the machine is fastened a guide-plate 10, Fig. 7, that has two longitudinal slots 11 and 13 for guiding each a bolt 12 or 14:, and also having two grooves 15 15, running partly parallel to the slot 13 and partly oblique to the same. Upon the right-hand part of the plate 10 there runs a slide 16, Figs. 8, 9, 11. 12, that carries two upright bearing-lugs 17, in which there bears a shaft 18, upon which oscillates a frame shaped clamping-bar 19, that is so influenced by a spring 20, surrounding the shaft 18, that its free end 19 lies upon the slide 16, and so holds fast a sheet of paper lying below it on the slide.

The rail of the clamping-bar 19, lying on the other side of the rotary shaft 18, is adapted to move under the free end of the twoarmed oscillating pressure-lever 21, which is secured to a shaft 22 and slides at the other end on the roller 2, which in the track of this scribed later on.

The longitudinal displacement of the slide is brought about by the lever 8, which has a guide-slot 24, in which a slide-piece 26 is adjustable by means of a screw-spindle 25 in the direction of the length of the slot. The piece 26 carries on the upper side a short cylindrical pin 27, Fig. 25, upon which one portion, 28, is capable of rotating freely and which embraces with its flanged edges 29 the counter-lever 31, oscillating at one end, 30, so that if the lever 8is made to move outward the counter-lever 31 must also move out to the same side, in which case the portion 28 slides along the lever 31.

The counter-lever31 is provided with a slot 32, in which a slide-piece 33 is movable. The latter is perforated to receive a pin 12, which carries a roller 34, riding in the slot 11 of the guide-plate 10, and is connected with the slide or pusher 16. In this Way the stroke of the counter-lever 31 produces a longitudinal displacement of the slide 16 in which the length of the displacement is governed by the magnitude of the angle of stroke. The latter is variable, however, by the adjustment of the slide-check 26 in the slot 24 of the lever 8, so that the length of the paper can always be exactly adapted for the tube that is to be manufactured. This arrangement therefore forms a regular measuring device by determining exactly the movement of the slide.

From the clamping device 16 19 the sheet of paper is acted upon by asecond similar arrangement. This consists of the slide 35, Figs. 13, 14, 19, 20, that moves in the left-hand side of the plate 10 and carries a support 37, having a longitudinal slot 36, as well as the bolt 14, extending through the slot 13. The slot is connected by a suitably-bent pull-rod 38 with the second oscillating lever 9, operated from the groove 3. Upon the slide 35 there rests a second slide 39, Figs. 15, 16, 19, 20, which has a bolt extending into the slot 36 of the lower slide 35 and also having two pins 41 41 extending into the slots 15 15 of the track 10. By these three bolts 40 41 41 the slide 39, that otherwise rests free on the slide 35, is positively guided in such manner that at the beginning of the movement to the left of the lower slide 35 it remains at rest relatively to the same, but on the further motion executes a movement at right angles to the previous movement@l. e., in the direction of the slot-and thus brings the sheet of paper to-the winding-spindle 42. The slide 39 carries two upright bearing-lugs 43, supporting a shaft 44 and capable of oscillating a clamping-bar 45, which is held down on the slide 39 permanently by a spring 46, coiled around the shaft 44. Upon the part'of the clamp-rail 45 that stands elevated in consequence of the spring action and that is formed into a slide- I the lever by the cam-surface the spring 46 again closes the clamp-rail 45.

The manner of operation of the device under the presupposition that it is already at work is as follows: Both slides 16 and 35 move together and have got back to their rearmost position, Fig. 1, with the rails 19 and 45 open. Now being released by the cam-surfaces 23 and 50 the clamp-rails 19 19 and 45 close and hold the paper fast, so that now the shears (not shown) come into action and can cut off the paper at the proper place. When this has happened, the groove 3 comes into action and by means of the levers 8 and 9 causes a longitudinal movement of the slides 16 and 35, in which case the length of the movement of the slide 16 is determined exactly by the stroke of the lever 31, while the slide 35 makes a uniform traversing movement. During this displacement the second slide 39 also moves in a direction perpendicular to the first movement, and so carries the paper exactly in front of the winding-spindle 42, which now seizes the same, whereupon the clamp-rail 45 opens and releases the paper. At the same time the rail 19 19 opens, and also the two slides 16 and 35 now move again into their rearmost position, whereupon the movements described are repeated. Attention is called to the fact that the paper during the cutting is held fast by both clamp-rails, so that the cutting is made sure and so that the length of paper cut off is always the same.

What I claim is 1. In a machine of the character described, the combination with a driving-shaft, and a roller carried thereby, of a rod movably operated from the roller in a longitudinal direction, a two-armed lever actuated by the said rod, a slide 16, an oscillatable clamping-bar carried by said slide, an oscillated lever actuated from the roller on the driving-shaftand operating to lift the clamping-bar from the slide as described, means intermediate the slide and the said two-armed lever whereby said slide is operated.

2. In a machine of the character described,

the combination with a driving-shaft, and a I rod, a slide 16, an oscillatable clamping-bar carried by said slide, an oscillatablelever actuated from the roller on the driving-shaft and operating to lift the clamping-bar from the slide, as described, a slide-piece 26 adjustably mounted in a slot in the two-armed lever, a lever 31 engaged by the piece 26, said lever 31 having a slot, a slide-piece 33 movable in the latter slot, a guide-plate l0 and a connection between the slide-piece and the guide-plate and also with the slide 16.

3. The combination with a driving-shaft and a roller thereon, of a two-armed oscillatable lever 9 operated from said shaft, a guideplate having slots 13, 15, a slide 35, the support carried by the slide and having a slot, a
